i ARMATURE-WINDING MACHINE- Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed October 23, 1905. Serial No. 284,051.

To all LUhOII'I/ it may concern:

Be it known that I, PAUL E. Osw'ALD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Machines for WVinding Armatures, of which the following is a specification.

My invention primarily relates to that class of armatures which are known as toothdrum armatures; and the object thereof is to produce a machine in which the coils of the armature may be quickly and easily wound: I accomplish this ob'ect by the mechanism described herein an illustrated in the accompanymg drawin s, in which- Figure 1 is a side elevation with parts broken away for clearness of illustration. Figs. 2 and 3 are details of certain of the parts shown in Fig. 1.

In the drawings, 5 is the base-plate of the machine, to which is secured a standard 6, the u per end of which is bifurcated and carries t e operating-shaft 7. On the outer end of this shaft is a driving-pulley 8, to which power is applied to rotate the shaft. On the shaft and within the furcations of the standard is a worm 9, which meshes with a gear 10, mounted on a shaft 11, secured to the standard. Gear 10 is revoluble on shaft 11, and

side thereof, as shown in Fig. 1, to show how many teeth there are between certain points. A pointer 12 is secured upon the end of shaft 11 by screws 13 upon which screw it may be revolved, so as to indicate how many times the worm rotates, as hereinafter explained. On the inner end of the operating-shaft is the armature-holding frame, which is composed of the base-bar 14, having slots 15 at the ends thereof, through which pass the adjusting ing bar 17 to the base-bar. The outer end of. the su portingbar is concave, and the shaft 18 of t e armature is received therein, and a strap 19 passes around the end of the armature-shaft and about the base-bar and is provided with a thumb-screw or set-screw 20, by means of which the armature-shaft may be securely attached to the armature-holding frame. A like strap is provided at the other end and a like supporting-bar. The slots in the ends of the base-bar permit-of the adjustment of the holding-bars on the basebar to rovide for armatures having shafts of different lengths. To the armature-shaft are secured the laminated toothdisks 21, whose teeth 22 are arranged so as to form channels 23 therebetween for the reception and retention of the insulated wire 24, which forms the winding of the armature.

A s )ool 25, containing the wire 24, is slipped upon a stud 26, secured to the baseplate, and the free end of the wire is secured to the armature-drum in the usual manner. A sup orting-standard 27 is secured to the base-p ate, and a rod 28 is 'slidably mounted in the top thereof. The outer end of this rod carries a turnbuckle 29, which is likewise connected to a rod 30, which is provided with a clamp 31, through which pass the arms 32 and 33 of the guide-frame. The bases of these arms are arallel, are adjustable in the clamp, and are eld in the clamp in their adjusted position by the set-screw 34. The outer ends of these arms are bent on an angle to the base and project toward each other and are staggered as to each other, one end of one arm being adapted to engage at the edge and at the end of one of the channels at one end of the drum, as shown on the upper side of the drum in Fig. 2 and also in Fig. 1, while the other arm enga es in a like osition at a similar channel at t 6 other end of the drum as many channels below the up er channel as desired, the number being ess than one-half the total number of channels.

I have found in practice that where the drum is provided with twelve channels the lower arm should engage the fifth channel below the channel at which the upper arm engages. In the ends of these arms are notches 35, which form small points on the ends of the arm, which are also tapered, as best shown in Fig. 3. One of these-points engages the end of the drum and the other the edge of the channel. A spiral spring 36 is mounted upon rod 28, and one end is secured to the turnbuckle and the other is secured to the standard 27, so as to provide a slight tension upon the guide-frame. When power is applied to drive-pulley 8, the armature is revolved, and as the guide-arms are in engagement with the armature they are revolved with it, thereby causing the guideframe to revolve. As the wirereels off the ,spool it is guided by the arms of the guideframe first into one slot or channel and then into the other channel .at which the other arm is set. Before the wire is wound the channels are lined with paper 37. The worm and gear are so arranged thatthe too would then rotate the index-finger t0 0,

and then shift his guide-frame to two other channels and then applypower until the nun:- ber 27 registered with the index-pointer, when he would again stop and shift, the guideframe to new channels and turn the indexpointer again to 0. He wduld proceed in this manner until all the channels were filled, when the armature would be wound.

He would then connect up the different bobbins in the usual manner.

Having described my invention, -what I claim as new, and desire to secure by Letters Patent, is.

1. The combination of an armature-holding frame; means to revolve the same; and a revoluble guide-frame having arms with the points thereof staggered and adapted to en gage the armature-drum at its opposite ends and at difierent channels therein.

2. The combination of an armature-hold ing frame; means to revolve the same; and a revoluble guide-frame having adjustable arms with the free ends thereof staggered and adapted to engage the armature-drum at its opposite ends and at diflerent channels therein.

3; The combination of an adjustable armature-holding frame; meanstorevolve the same; and a revoluble guide-frame having adjustable arms, the free ends of which approach each other and are staggered and are adapted to engage the armature-drum at its opposite ends and. a different channels therein.

4. The combination of an armature-holding frame; means to revolve the same; a revoluble guide-frame having arms with the points thereof staggered and engaging the armature-drum at its opposite ends and at different channels therein; and means to give a tension to said guide-frame 5. An armature-Winding machine comprising a base-plate a standard secured thereto; an operating-shaft having a'worm secured thereto revolubl mounted in said standard;

a gear revoluby mounted on a shaft se-.

cured to said standard and having certain of the teeth thereof numbered, said gear meshing with'said worm; a pointer revolublysecured to the shaft upon which the gearis J mounted; 'an armature holding frame secured to said shaft; and a revolubly-mounted guide-frame secured to said base, said guide frame having arms, the free ends of which.

are staggered and engage the armature-drum at'its opposite ends and at different channels therein.

In witness that I claim the foregoing I have hereunto subscribed my name this 16th day of October, 1905.
